Abstract: ABSTRACT This invention relates to a mode change-over mechanism for a tape recorder, in particular for the rapid feed mode and rewind mode of a tape recorder.  The device of this invention decreases the number of parts hitherto needed for switching the motor and rolls, and moreover ensures reliable mesh-ing between the gears, thus overcoming slipping problems associated with con-ventional mechanisms.  The present mechanism has a feeder reel and take-up reel which have gear elements at their respective peripheral surfaces.  A rapid feed gear meshes with the gear element relating to the take-up reel, and a rewind gear meshes with the rapid feed gear and with the gear element at the periphery of the feeder reel.  The rapid feed gears are connected to a drive motor and when moving, rotate to connect with the gear element of the take-up reel.  The rewind gear, when moving, connects with both the rapid feed gear and the gear element of the feeder reel.  This co-action achieves posi-tioning of the rapid feed gear and rewind gear.

Abstract: ABSTRACT OF THE DISCLOSURE          A concrete float having a buoyant foam core sur-rounded by a concrete shell.  The deck of the shell has inte-grally formed therewith a plurality of transverse ribs and longitudinal ribs which strengthen the deck.  Consequently, the necessary strength for the deck can be achieved by util-izing a substantially reduced quantity of concrete.  A tubu-lar conduit extends beneath at least some of the transverse ribs.  The conduits are provided in order to receive tie rods having their ends projecting from the sides of the float and through elongated wales which serve to secure the floats to each other.  The concrete is preferably reinforced with con-ventional concrete reinforcing bars.  The float is formed by placing a rectangular block of foam in a rectangular form after a layer of concrete has been poured in the form with the foam core being positioned apart from the sides of the form. Transverse and longitudinal grooves are formed in the upper surface of the core, and tubular conduits are placed in at least some of the transverse grooves.  Finally, sufficient concrete is poured into the form to fill the sides and cover the upper surface of the foam thereby filling the space be-tween the core and foam.  The concrete also fills the grooves in the foam thereby creating the transverse and longitudinal ribs and securing the tubular conduits in position within the transverse grooves.

Abstract: Abstract of the Disclosure The scanning drum of a facsimile receiver carries a longitudinally extending stripe such that portions of the stripe at opposite extremities of a document carried by the drum are exposed.  The width of the stripe at the exposed portion adjacent the leading edge of the document is sensed by an optical sensing head and stored in memory prior to transmitting dark/light variations in the document.  The scanning of the document continues until the optical scanning head is juxtaposed to the exposed portion of the drum adja-cent the trailing edge of the document.  At this time, the width of the stripe is again detected and compared with the width in memory so as to verify that the scanning of the document is complete.  The facsimile transmission is then terminated.

Abstract: 108,125 ELECTROPHOTOGRAPHIC COLOR PROOFING APPARATUS      ABSTRACT OF THE DISCLOSURE                 An electrophotographic color proofing apparatus including a copyboard carrying a color separated positive and capable of being positioned into intimate contact with a charged photoconductive coating of an electrophotographic member.  The engaged members are exposed to light, discharging the coating in increments to form a latent electrostatic image thereon.  The copyboard is withdrawn and the exposed electrophotographic member rotated 180 degrees facing toward a toning assembly consisting of a row of plural toning units, each carrying a different color toner and arranged in line for linear translation below the exposed electrophotographic member with a selected one toning unit thereof being activated to apply a selected color toner to the latent electrostatic image.  The toned member again is revolved 180 degrees.  A pre-wet transfer medium in the form of print paper stock is engaged with the toned member for transfer of the toned image, preferably by drawing a roller across said member while employing a simultaneous electrical bias.  A full color proof can be obtained by repeating the cycle, activating successive individual toning units of the assembly and using the same sheet of transfer medium.     Registry of plural images applied to a single sheet is effected mechanically, as by upstanding pins provided on the support for electrophotographic member and/or the copyboard.  Provision is made to clean both the photo-conductive surface and the bias plates of the toning units of excess and/or residual toner.
